Talk:Mach reflection

The introductory sentence is "Mach reflection can exist in both unsteady or pseudosteady flow, as well as in steady flow."

I don't understand this sentence.

Can someone who is knowledgeable provide an alternate introduction to the topic? Perhaps it could start with a definition. Mark.camp (talk) 01:54, 19 April 2011 (UTC)
